Thanks for your reply's....

HappySmoke, I will be sure to keep you posted. Blondie has just begun her dark period so i will switch her into the other room under the Son Agro right now. When she wakes up, she will see the world in a whole new light....lol. And it has had barely any usage. My buddy said he went through two or three flowering stages with it.

Ziggy, When i was trying to figure out if this was safe, i called my local hydro store and asked them what they thought. They said; "Their is no 430W Ballast, they are just trying to make extra money of you online, using a 400w HPS ballast with something extra they put it to make it use the extra 30w (supposably very cheap online)". They told me to pop it in my 400w ballast and it will make a HUGE difference on yield and density. They also said something that really made me think.. "If you were already using a 400w HPS, than whats the problem with keeping the 400w with an added blue light spectram which will greatly improve your crop? What are you gonna do with the extra 30w anyways?" This REALLY put me in check. This is the way to go. Ide say, if you already have some 400w HPS ballasts keep them and just buy the bulb (http://www.gtghydroponics.com/store/0-0-600.htm). And if you dont, just buy two bulbs and two 400w ballasts, instead of spending alot of extra money on a little bit of light. But thats just my 2 cents........
